BOBBlN-STAND.

SPECIFICATION forming part of Letters Patent No. 363,671, dated May 24,1887.

Application filed February i4, 1887. Serial No. 227,497. (No model.) i

To LZZ whomi may concern,.-

Be it known that I, ARTHUR WV. PARK HURsT, a citizen of the UnitedStates, and a resident of Milford, in the county of Hillsborough andState of New 'Hampshire have invented certain new and usefulImprovements in Bobbin-Stands; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled inthe art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification, and in which Figure 1 is aperspective Aview of my improved bobbinstand. Fig. 2 isa verticalsectional View of the same, partly in elevation.

Fig. 3 is a vertical sectional View of the base through a plane at rightangles to the view shown in Fig. 2; and Fig. 4 is a perspective detailview of the spindleconc spring and sleeve-whirl removed from the frame.

n Like letters ofreference denote correspondlng parts in all theiigures.

My invention relates to bobbin stands, or the frames for holding thespools or bobbins used inspoolers, warping-machines, spinningmachines,reeling-machines, and other machines or devices of a similar nature inwhich bobbins are used; and it consists in the de*- tailed constructionand combination of parts of a device of that class, which will behereinafter more fully described and claimed.

In the accompanying drawings, theletter A denotes the frame of myimproved bobbinstand, of which B is the base-plate. This base piece isprovided with a cylindrical box, C, which may be reenforced by arib orweb, D, connecting it with thc base of the vertical standard E, at theupper end of which is the usual arm, F, projecting at right anglesparallel to the base B and rib D.

Inserted into the central bore or recess in the box O is a cylinder, G,one side of which is flattened or cut away, as shown at H. This iattenedside of the cylinder` faces a screwthreaded aperture, I, in the box C,into which is inserted the set-screw or binding-screw J, the inner endof which should press lightly lagainst the flat part of cylinder G. Thebottom of said cylinder is recessed, as shown at K, to fit the upper endof a spiral spring, L, the lower end of which .rests in a recess, M, inthe baseplate ot' thc frame A.

The upper part of cylinder G is reduced, so as to form a shoulder oroffset, N, and the top of said reduced part terminates in a cone, O. Thecylindrical reduced part of cylinder G, below said cone, is providedwith a loose sleeve or collar, P, forming a truncated cone adapted torevolve freely upon the shoulder' N, on which it rests.

Inserted through the outer end of the upper horizontal arm, F, is theusual conical upper bearing, Q, which may be adjusted by'means of ascrew, It, in a well-understood manner, so as to t into the recess inthe head or upper end of the bobbin S.

Upon one side of the standard E is soldered or otherwise fastenedaspring, T, formed with a coil, U, to give the free end of said springthe requisite tension or bearing against the yarn on the spool orbobbin. The free end of said coiled spring T U is bent to form a loop,as shown at V, of such shape that it will bear evenly against the yarnon the spool or bobbin.

The lower end of the bobbin has a conical recess, W, adapted to tit uponthe cone O-P and revolve with the sleeve P of said cone. As the centralpart, O, of the cone is stationary and does not revolve, it operates tohold the spool or bobbin in a steady vertical position, whilethe sleevel?, against which the lower end of the bobbin rests, revolves with it,spring L operating to push the conical sleeve l) against the lower endof the .bobbin with sufficient pressure to cause the requisite frictionand contact.

It will be seen that the bobbin may be removed f rom the stand in amaoment of time simply by pressing it in a downward direction, so as todepress spring L in its recess and thus release the upper end of thebobbin from the cone. Similarly, the bobbin may be replaced in a momentof time.

Itis obvious that the arrangement herein shown and described may bereversed, and that the cone and whirl, with their actuating-spring, maybe arranged in the upper part of the stand-viz., in the bearing`Q-without deviating from the spirit of myinvention, in which case, ofcourse, the screw R and ils appurtenances are arranged in the base. Bymeans ofthe spring Tan even pressure will be brought to bear upon theyarn as it is reeled off of the bobbin, so that this will also be foundto Work evenly and satisfactorily under all circumstances.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States-h 1. The combination, in abobbinsand, of a standard the upper end of which is provided with an armand a bearing, the recessed box, the spring arranged Withinsaid recess,the vertically-sliding` cylinder flattened on one side, having a reducedupper portion terminating in a cone, a set-screw adapted to bear withits inner end against'thetlattencd part of thecylinder, and the conicalsleeve rotating upon the reduced part of the cylinder, substantially asand for the purpose set forth.

2. The combination, in a bobbin-stand, of the standard, the cone shapedsleeve, the Spring, the solid cylinder terminating ina cone and forminga bearing for the sleeve, the tension-spring bearing with its free endagainst the yarn upon the bobbin, and the adjustable bearing arranged inthe stand opposite to the sleeve, substantially as and for the purposeshown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaflixed my signature in presence of two Witnesses.Y

ARTHUR W. PARKHURST.
